ABSTRACT:
The present invention provides network polymers obtained by curing compositions that comprise an ester with at least two terminal epoxy groups. Preferred esters include those represented by the formula (1), wherein each R1independently represents a substituted or unsubstituted homoaliphatic or heteroaliphatic group; A represents a substituted or unsubstituted homoalkylene, hetemalkylene, arylene, or heteroarylene segment; and n represents an integer equal to or greater than 2.
